Industrial Park - Chlorinated Solvent Allocation Modeling Using Forensic Analysis & Geographical Information Systems (GIS).

DPRA combined analytical results and sample location data using Geographical Information Systems (GIS) to form a visual representation of site conditions. This provided an efficient resource for our expert witness to form legally defensible opinions.
Drycleaners - Forensic Investigation of Chlorinated Solvent Plume and Litigation Support, Los Angeles, California.
DPRA was engaged to forensically evaluate site conditions and develop cost allocation and other investigative strategies. DPRA’s geographical information system (GIS) team compiled an electronic database of historic and current data to form legally defensible opinions. In addition, Zymax Forensic Laboratories (a subsidiary of DPRA) utilized its proprietary method to analyze PCE, TCE, and DCE carbon isotope ratios in soil and groundwater at the facility.

Drycleaners - Forensic Investigation of Chlorinated Solvent Plume and Litigation Support, Lodi, California.  

DPRA was engaged to assess and determine the cause of PCE contamination discovered in the City of Lodi’s water supply. DPRA reviewed hundreds of technical environmental reports; soil-vapor, soil and groundwater analytical data; deposition transcripts; and regulatory correspondence. Soil-vapor, soil and groundwater analytical data was incorporated into a Geographical Information Systems (GIS) visual platform and DPRA was able to provide opinions as to the source of the contamination.

Chemical Distribution Facility - Forensic Investigation of Chlorinated Solvent Plume and Litigation Support, Billings, Montana. 

DPRA was hired to provide expert opinions and environmental forensic analysis to determine the origin of contaminants and timing of the releases. DPRA reviewed thousands of pages of environmental reports, regulatory correspondence, facility operational documents, interrogatories and responses, electronic data summarizing chemical test results at the Site, aerial photographs and deposition transcripts. A Geographical Information System (GIS) project was also developed which presented historical and current analytical data for multidimensional analysis.
